One way - the && || stuff acts like an "if then else"
Code:
string="plplqabl fghj"
myletter="a"
echo "$string" | grep -q "$myletter"  && echo "$myletter found" || echo "$myletter not found"

myletter=x
echo "$string" | grep -q "$myletter"  && echo "$myletter found" || echo "$myletter not found"

Code:
STRGZ="hello world!!!"
LTR="w"
echo $STRGZ |  awk -vc="$LTR" '{if(gsub(c,"")) print "Found";else print "Not Found"}'
